[0059] Figure 2 This is a schematic flowchart illustrating a specific use of a method according to an embodiment of the present invention;
[0060] Figure 3 This is a schematic structural block diagram of a system according to an embodiment of the present invention. Detailed Implementation
[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0062] like Figure 1 As shown, this invention provides a method for controlling an electric door in an automobile. The method is applied to an automobile equipped with an electric door and a concealed door handle. The method includes the following steps:
[0063] S1. Real-time detection of whether there is a car key around the car, and when the car key is detected around the car, control the electric door to unlock and control the hidden door handle to pop out, and then execute step S2.
[0064] Specifically, the present invention detects whether there is a car key around a car, including:
[0065] Send a preset low-frequency signal around the car;
[0066] It receives verification information returned by car keys around the car.
[0067] Compare the returned verification information with the verification information of the car key corresponding to the current car:
[0068] If so, then there is the car key for the current car around the car;
[0069] If not, then there is no car key for the current car around the vehicle.
[0070] In practice, those skilled in the art can set the aforementioned preset low-frequency signal according to actual needs.
[0071] In this embodiment, the preset low-frequency signal is a 125KHz low-frequency carrier signal.
[0072] When the step S1 is executed, the automobile sends a 125KHz low frequency carrier signal outward, and receives the verification information returned by the automobile key around the automobile, and the automobile compares whether the verification information returned by the automobile key is consistent with the automobile key verification information corresponding to the automobile stored in the automobile, if yes, the automobile key of the current automobile exists around the automobile, the electric door of the automobile is controlled to be unlocked, and the hidden door handle is controlled to be popped out, and then the step S2 is executed, if no, the automobile key of the current automobile does not exist around the automobile.
[0073] It should be noted that the automobile key verification information of the automobile and the automobile key of the automobile is stored in the automobile and the automobile key of the automobile respectively, and the automobile key verification information of the same automobile has only one.
[0074] S2, whether the hidden door handle is triggered is detected, if yes, the step S3 is executed, if no, the detection is continued, if the hidden door handle is not detected to be triggered within a set time length, the hidden door handle is controlled to be restored to the original position, and the electric door is controlled to be locked.
[0075] Specifically, the skilled person in the art can set the set time length according to actual needs.
[0076] For example, the set time length is 2 minutes, when the step S2 is executed, whether the hidden door handle is triggered is detected, if the hidden door handle is detected to be gripped by the user, the step S3 is executed, if the hidden door handle is not detected to be triggered, the detection is continued, and if the hidden door handle is not detected to be triggered within 2 minutes, it is determined that the user has no intention to get on the automobile, the hidden door handle is controlled to be reset, and the electric door is controlled to be locked.
[0077] S3, whether the automobile key is valid is detected, if yes, the electric door is controlled to be automatically popped open, if no, the hidden door handle is controlled to be restored to the original position, and the electric door is controlled to be locked.
[0078] Specifically, the method for detecting whether the automobile key is valid comprises:
[0079] sending a preset high frequency signal around the automobile;
[0080] corresponding to receiving the verification information returned by the automobile key around the automobile;
[0081] comparing whether the returned verification information is consistent with the automobile key verification information corresponding to the current automobile:
[0082] if yes, the automobile key is valid;
[0083] if no, the automobile key is invalid.
[0084] Specifically, the skilled person in the art can set the preset high frequency signal according to actual needs.
[0085] In this embodiment, the preset high-frequency signal is a 433MHz high-frequency signal.
[0086] When step S3 is executed, the car sends out a 433MHz high-frequency signal and receives verification information returned by car keys around the car. The car compares the verification information returned by the car key with the verification information of the car key corresponding to the car stored in the car. If they match, the car key is confirmed to be valid and the car's electric door is controlled to open automatically. If they do not match, the car key is confirmed to be invalid, the hidden door handle is controlled to reset, and the electric door is controlled to lock.
[0087] For example, the electric door is equipped with an unlocking light. When the hidden door handle on the electric door pops out, the unlocking light on the electric door flashes to remind the user that the electric door has been unlocked.
[0088] In practice, those skilled in the art can set the number of times the unlock light flashes according to actual needs, such as setting the unlock light to flash 2 times, 3 times, or other required times.
[0089] For example, the electric door is also equipped with a welcome light, which lights up when the electric door automatically opens to facilitate the user getting into the vehicle.
[0090] To facilitate understanding of the present invention, the following description further illustrates the automotive electric door control method provided by the present invention, based on the principle of the method and the usage control process of the automotive electric door in the embodiments.
[0091] Assuming the above-mentioned time duration is 2 minutes, such as Figure 2 As shown, the automotive electric door control method includes the following steps:
[0092] The system detects and determines if a car key is present near the vehicle. If a key is found, it unlocks the power doors, pops out the concealed door handles, and activates the unlock indicator light. It then checks if the concealed door handle is triggered. If not, the system continues checking. If no trigger is detected within two minutes, the concealed door handles reset, and the power doors lock. If the concealed door handle is triggered, the system checks if the car key is valid. If valid, the power doors open automatically, and the welcome lights illuminate. If invalid, the concealed door handles reset, and the power doors lock.
